Q: Yosemite 10.10.2 update USB keyboard not recognised
Just installed Yosemite update 10.10.2 on my iMac 5k machine. The attached USB keyboard no longer functions. I've attached the keyboard to my macbook pro, works perfectly. I've screen shared into my Mac, performed disk utility checks, NRAM & SCM resets, still not working.
For the moment I have a £3500 paper weight. :O(
iMac with Retina 5K display, OS X Yosemite (10.10.1), OS X 10.10.2

Hello, please see if it works when you connect the USB extension cable. It should have been in the box when you bought your Mac.
